Abstract
Composite transparent conductors are described, which comprise a primary conductive medium based on metal nanowires and a secondary conductive medium based on a continuous conductive film.
Claims16
A composite transparent conductor comprising:
- a first layer of a primary conductive medium comprising a first type of electrically conductive nanostructures, wherein:
- a plurality of the first type of electrically conductive nanostructures are below an electrical percolation threshold, and
- the primary conductive medium has a first mesh size;
- and
- a second layer of a secondary conductive medium contacting the first layer of the primary conductive medium, wherein:
- the secondary conductive medium is vertically conductive so as to equalize an electrical potential distribution in the composite transparent conductor, and
- the secondary conductive medium has a second mesh size at least five times smaller than the first mesh size.
